The Centurions

Crystal Kane, computer scientist, and her team of top-secret warriors called Centurions try saving the world from destruction at the hands of Doctor Terror's Doom Drones. The Centurions each have their own exoframe armors and weapons. The team consists of the aquatic combat expert, Max Ray; the surface combat expert, Jake Rockwell; and the air combat expert, Ace McCloud. They fight Dr. Terror and Hacker, advanced cyborgs whose gole is to take over the world. The Centurions' headquarters, SkyVault, is a ship orbiting the earth, from which they transport to the surface when needed. When the Centurions shout "PowerXTreme!" their Assault Weapon System is charged to their ExoFrames. It also is beamed down from SkyVault by Crystal Kane.

And here's lots of new info below, courtesy of Matt Brough from the UK. Thanks, Matt!

Each of the original three team members, Ace McCloud (Air), Jake Rockwell (Land) and Max Ray (Sea) actually had multiple weapon systems that could be connected to their suits. The suits themselves were known as 'exoframes' and each weapon system was individually named (see below). They weren't technically computer operated rather a fusion of man and machine, with the Centurions' consciousness superceding that of the mechanics. This directly contrasted with Doc Terror's Doom Drones which were often implied to be cyborgs with the machine controlling the organics, something he appeared reluctant to do to his fully human daughter, Amber.

I don't really know much about the final series, except that the Centurions' received a bunch of new weapon systems and two new members: Rex Charger, energy expert, and a Native American called something like Johnny Nightwolf, their infiltration expert.

Ace McCloud's Weapons Systems:

Sky Knight

Small, lightly armed jet pack like air assault system with cool arm missles and a chest mounted bomb

Orbital Interceptor

Non-Atmospheric craft, usually for space missions, but was used underwater on at least one episode
